Patented Apr; 4, 1916.

Application led October 28, 1913. Serial No. 797,836.

T0 all whom t may concern: a

Be it known that I, GUY SMYTr-I, a citizen of the United States, residing at Shawneetown, in the county of Gallatin and State of Illinois, have invented new and useful Improvements in l/Vell-Pumps, of which the following is a specification.

This invention relates to improvements in pumps and especially with relation to improvements on the pump invented.by me and for which I have filed an application for Letters Patent of the United States, June 14, 1913, Serial No. 778,683, one object of vthe invention beingto effect improvements in the construction of the pump casing and cause the casing to form a housing for the operating mechanism of the pump plungers, another object being to effect improvements in the construction of the delivery pipes whereby the same are adapted to be longitudinally adjusted according to the depth of the well in which the pump is used.

This invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawing: Figure 1 is a vertical central sectional view of a pump embodying my improvement. Fig. 2 is an elevation of the upper portion of the pump. Fig. 3 is partly a plan and partly a horizontal sectional View of the same. Fig 4 is a detail sectional view on an enlarged scale of one of the delivery pipes.

In accordance with my invention I provide a casing 1 which is here shown as having parallel sides 2 and semi-circular end walls 3. The casing has a base L adapted to be bolted or otherwise suitably secured on a well platform and the casing is provided at its upper side with a removable cover 5, and with a discharge pipe 10 which terminates in a spout 11 and is provided with an air chamber 12. A pair of short pipe extensions 18 are formed on the lower side of and depend fro-m the base and are provided at their lower ends with unions 14 to which are detachably secured the upper members 15 of the suction pipes 16, each suction pipe also comprising a lower member. The lower suction pipe members 17 are connected to the upper ends of a pair of cylinders 1S in which operate a pair of pump plungers 19. The lower ends of said cylinders are connected together by a semicircular branch in the pipe 20 which has an intake duct 21 at its Alower side.

The pump rods 22 which are attached to the pump plungers are pivotally connected to a rocker 24 the shaft 25fof which is mounted in bearings 26 in the sidesofthe casing. One end of the said shaft projects outwardly from the casing and through a stuffing boX 23 and a lever handle 27 is secured to the projecting end of said shaft and is adapted to be manually operated to actuate the rocker and hence also operate the pump plungers. Check valves 28 are in the lower ends of the pum-p cylinders. By the` provision of the casing and its removable cover the operating mechanism of the pump is housed, concealed from sight and effectually protected. The delivery pipes being longitudinally adjustable are adapted to be adjusted according to the depth of the well, in which the pump is used. The upper member 15 of each delivery pipe is tted with a tubular sleeve 29 which is vertically adjustable thereon and may be secured thereto at any desired adjustment by means of a set screw 80. v'Ihe sleeve is provided with an annular flange 31.Y

The upper end of the lower member 17 of each delivery pipe is enlarged as at 32 to receive the lower portion of the upper member 15, such enlargement being of suitable length to admit of the required adjustment of the pipe members with rvrespect to each other and at the upper end of the enlarged portion of each pipe member 17 is an outwardly extending flange 33 which is detachably secured to the flange 2 of the sleeve 29 by means of bolts 811-. Hence the suction pipes are adapted to be adjusted longitudinally and the members of the suction pipes may also be detached from each other when desired.

Having thus described my invention, I claim In a well top, in combination, a base, said base being formed with a pair of openings, said casing having a bottom secured upon said base, integral pendant cup-shaped members formed integrallyupon said casing and by said cup-shaped members, a nipple- 1' stier' seg.;

formed between the top and bottom of seid rocker arm and projecting through said cupcasng, a discharge pipe connected to said shaped members and tube. 13 nipple, a top secured upon said casing and In testimony whereof I afix my signature closing the same,V a shaft extending transin the presence of tWo Witnesses.

versely of said casing, a rocker arm ful- GUY SMYTH. crumed :it a central point upon said casing, and L reciprocating plunger rod pivotally connected to the opposite ends of seid Witnesses:
